I really need your opinion and to make a comparison looking at comfort, efficiency, portability, noise isolation and sound quality and detail, bass, lows, mids, and highs, etc.

Please also write the list from best to worst rated on sound quality. Sound quality is top priority for me.

For example are K167 and K267 better than Beats Pro, K550 and Momentum?

Your list of headphones is too long. You likely won't find many people on the forums who have extended experience with all 10 headphones you just mentioned.

To receive a more informed recommendation, you should list your priorities in order, the genres of music you listen to, the primary usage of the headphones (work/home/portable) and what you define as "sound quality". You have a ton of bassy headphones on there, so if I infer correctly it would be silly to recommend a neutral headphone despite it having great sound quality to me.

I don't want portability (primary usage) to be a major factor. It doesn't really matter to me where I'll be using it. Sound quality. I would prefer the bass to be powerful but without ruining the song by being too powerful. I would prefer, although as you mentioned if the headphone was neutral but it had a great sound quality, please share your opinions.

I know that my list is too long but I just wanted some opinions on any of them and comparisons between any of them to get an idea.

I have tried some of them like the Denon AHD600 and D400 and the Momentums but nowhere near enough to get an idea and have preferences, except for the Denons maybe having a richer sound than the Momentums.

Same goes for the AKG K550, I have basically just tried the clamping force. And now the release of the K167 which I really like and the upcoming K267.

Heya,

K167 now, or K267 when it's released will probably please you for what you're looking for.

Alternatively the D600, if you like the sound, is a decent headphone (simply pricey right now, still new).

Since Beats Pro are the only headphones I actually know the sound of, I wanted to know which headphones above would you hear a significant difference (in a good way), without being an audiophile and being a noobie like me? From reading around I learned that the K550 are much much better than Beats Pro sound wise and you hear a big difference. I don't know about the K167 and the Ultrasone Pro 900 and the others in the list so again that's why I asked.Are tee K167 better than Beats Pro siundwise and K550? What about the Ultrasone Pro 900?

Cant comment on the K167 or K550, but I own the PRO900 and listened to the Beats PRO. The PRO900 smoke the Beats pro in every way possible. They are in two different leagues... The PRO 900 has amazing bass, which never gets loose or sloppy. It's tight with a whole lot of punch and quantity, and doesnt interfere with the mids and highs whatsoever. The Beats pro is just bass, nothing else imo. I also hear great things about the K550 being extremely balanced and detailed.

Mmm...nice. I know that the Pro 900 are awesome headphones. So anyway the very best of the group would be the Pro 900 and the K550s, how do the Pro 900 do for portability. better or worse than K550, and is the sound as detailed as the K550? And is it actually true that the K550's clamp is adjustable? What about the K167, is the sound and noise isolation even comparable to these last two?
